I wanted to repost the fix found by Mtdew332 from over on the general forums:
-------------------------------------------------------------------
Possible soultion copy/pasted from
HERE
For those who have the problem where their decisions don't carry over:
-Possible Fix-
The game stores a "prefs.prop" in two places. One in:
C:\Users\___\Documents\Telltale Games\The Walking Dead
And the other in:
D:\STEAM\steamapps\common\the walking dead\Pack\default
Or if you don't have the Steam version, its somewhere in your game DIR.
Do backups before overwriting anything.
Copy the prefs.prop file from your game's DIR folders, and overwrite it in your Documents\TTG\TWD folder
Go in game and load the save game with your finished EP1. Switch to EP2 in the chapter select and run it.
This worked for me when any other solution did not. My decisions carried over.
------ ---------------------------------------------------------
This worked for me too, with one caveat: the line
D:\STEAM\steamapps\common\the walking dead\Pack\default
is not the default location of Steam games. This one is:
C:\Program Files (x86)\Steam\steamapps\common\the walking dead\Pack\default
Of course, if you've installed your Steam games directory in some place other than default, one assumes that you remember where and can find it again...
But once again, great find and I hope the Mods sticky this or add it to the FAQs or something to make it easier to find for the many of us who suffered from this problem!
